Product Summary for sFRP-1 Antibody

Immunogen

sFRP-1 Antibody was prepared from whole rabbit serum produced by repeated immunizations with a synthetic peptide corresponding to a 12 aa region of human Sfrp1 protein. (Uniprot: Q8N474)

Reactivity Notes

A BLAST analysis was used to suggest reactivity with this protein from human based on 100% homology for the immunogen sequence. Expect cross reactivity with sFRP-1 from mouse, rat and bovine sources as only a single amino acid residue change is found within the immunogen sequence (91% positive by BLAST). Cross reactivity with sFRP-1 homologues from other sources has not been determined.

Description

This affinity purified antibody is directed against human SFRP protein. The product was affinity purified from monospecific antiserum by immunoaffinity purification

Store vial at -20C prior to opening. Aliquot contents and freeze at -20C or below for extended storage. Avoid cycles of freezing and thawing. Centrifuge product if not completely clear after standing at room temperature. This product is stable for several weeks at 4C as an undiluted liquid. Dilute only prior to immediate use.

Scientific Data Images for sFRP-1 Antibody

Western Blot: sFRP-1 Antibody [NB600-499]

Western Blot: sFRP-1 Antibody [NB600-499]

Western Blot: sFRP-1 Antibody [NB600-499] - Analysis of a band 37 kDa (arrowhead) corresponding to SFRP1 in lysates from human cultured airway epithelial cells. Lysates were run on a SDS-PAGE and transferred onto nitrocellulose followed by reaction with a 1:230 dilution of anti-SFRP1 antibody overnight at 4C. Signal was detected using standard techniques.

Background: sFRP-1

SFRP1 (also known as FRP, FRP1, SARP2, Secreted Apoptosis-related Protein 2, Secreted Frizzledrelated Protein and Secreted frizzled-related protein 1) is a member of the SFRP family that contains a cysteine-rich domain homologous to the putative Wnt-binding site of Frizzled proteins. SFRPs act as soluble modulators of Wnt signaling. SFRP1 and SFRP5 may be involved in determining the polarity of photoreceptor cells in the retina. SFRP1 is expressed in several human tissues, with the highest levels in heart.
